Dr. Frank Kameny is the most famous former astronomer that astronomers don't know. Within the gay rights' community, he was a pioneer: co-founder of the Mattachine society (an early gay rights organization); a scientific conscience that challenged the American Psychiatric Association's classification of homosexuality as a disorder as grounded in prejudice rather than science; an agitator to remove the ban on gays from serving in the government or holding security clearances. Moreover, Dr. Kameny was a moral force who led by example, showing that gay people didn't need to hide in the shadows, grateful not to be beaten up. Rather, we could stand up and demand fair treatment and equality. For most of the last 50 years, that was a radical notion.
Two new Facebook groups seek to recognize Frank's accomplishments. You can buy him a drink to thank him for his activism (actually it helps pay his utilities, but who's counting?), or you can support the creation of a Frank Kameny prize by the American Astronomical Society.
